Document Description
Request to operate a methane digester on a 482.4± acre parcel located in the General Agriculture (A-2-40) zoning district. The methane digestor will process dairy waste produced from the on-site dairy and from an off-site dairy located just west of the project site (APN: 002-003-024), which will be piped in a slurry form via underground pipeline located across private property. As part of this request, the following improvements and structures will be developed on the project site: a 1.3± acre digester and associated equipment; a livestock water recycling system; biogas upgrading equipment; three natural gas generators; a backup/emergency flare; fire suppression water supply tank; and a 360± square-foot office, and a 1,500± square-foot shop. No new structures are proposed to be installed on the off-site dairy. No expansion of existing herd sizes will occur as a result of this project on either of the dairies. The dairy waste slurry will be processed through the digester and associated equipment by a gas collection and water filtration system to convert greenhouse gases (GHG) to Renewable Natural Gas (RNG), which will be trucked off-site via a heavy-duty truck. The dairy waste slurry from the off-site dairy (APN: 002-003-024) to the west of the project site will be pumped to the digester site via a private underground pipeline not within the County right-of-way. Slurry coming out of the digester will be piped back to each respective dairy pursuant to the quantities listed under each dairies’ current wastewater management plan (WMP); no net increase of wastewater will be applied to any of the dairies. Manure solids will be filtered out and used for normal dairy operations including bedding and crop fertilizer at each dairy. The project site is currently improved with a dairy facility, residential, and accessory structures totaling 650,506± square feet of building space consisting of four milk barns, a commodity barn, a bunker silo, three free stall barns, a heifer/maternity barn, a hospital and horse barn, a carport, three agricultural storage buildings, three cattle shades, three single-family dwellings, a swimming pool, and one duplex with a garage. The South San Joaquin Irrigation District (SSJID) Canal and Howell Lateral cross the project site from north to south, and the Fairbanks Lateral and Leitch Lateral cross from east to west on the project site. The digester will operate 24 hours a day/seven days a week. A maximum of three employees are anticipated on-site five days a week, from 6:00 a.m. to 5:00 p.m. The third employee will be on-site as needed throughout the week during the same proposed hours of operation. The applicant anticipates up to three roundtrips per day for trucks transporting RNG off-site to an existing pipeline connection in Helm, California where it will then be compressed and used as natural gas for fueling vehicles. Two heavy-duty truck trips per week are expected for system maintenance and refueling the natural gas generators to be installed on-site. The project site is currently served by private well and septic systems. The project site has existing access from County-maintained Dodds Road.
